摘要： It is an object to provide gas-insulated switchgear that occupies less installation space, in which the number of bellows to be used can be reduced, and that can minimize a work range in disassembling at addition or accident, and in reassembling. In double-bus gas-insulated switchgear in which a bus-side device is arranged above a breaker to reduce installation space to be occupied, a bellows is arranged between bus-side devices arranged vertically to each other, and under a support frame of the breaker, another support frame that can be separated therefrom is arranged, thereby enabling disassembling of a lower bus-side device alone.

摘要： The number of wirings and the number of switching elements are decreased in a heater, a sensor, and the like. First to ninth heaters that heat a hot plate are connected into a matrix form between first power lines in a row direction and second power lines in a column direction. The first power lines are connected to one end of a power supply through three switching elements, respectively. The second power lines are connected to the other end of the power supply through three switching elements, respectively. On-off control is performed to the switching elements to select the heater to be driven. Therefore, the number of power lines and the number of switching elements are decreased compared with a conventional technique in which the heaters are separately wired.
